Installation
1. Install the pump in a sump pit with a minimum
diameter of 10” (254mm) for models equipped with
vertical switches and 14” (356mm) for tethered
float switch models. The sump depth should be 15”
minimum (381mm). Construct the sump pit of tile,
concrete, steel or plastic. Check the local codes for
approved materials.
2. NOTICE: When installing the vertical switch, the
rod stop (Ref. No. 1F, Repair Parts) must not be
pushed up farther than the bottom nib on the float
rod. Pushing it any farther up the rod will cause the
switch to hang up on the pump discharge and will
damage thepump.
3. The pump should not be installed on clay, earth or
sand surfaces. Clean the sump pit of small stones
and gravel which could clog the pump. Keep the
pump inlet screen clear.
